TECHNOLOGY


STUDY OF ENVIRONMENTAL PROPERTIES OF GREEN-HOUSE TECHNOLOGY

The philosophy of Earth sheltered construction is based on three fundamental principles: energy saving, energy recovery and drawing energy from the environment, by exploiting, among other things, the building’s thermal mass. Thermal Mass is different than heat transfer resistance. R-Value is heat transfer resistance only. Typical R-value for earth is 0.25 per inch; however, the thermal character of the soil mass is quite different than that of material designed and used primarily for heat transfer resistance (R-value) like polystyrene or polyurethane foam. When changing from soil to a less massive "insulating" material, you should understand the design performance with regards to heat capacity of the building and/or soil mass (K-value). A massive soil wall or roof can store heat energy to even out the temperature swings of day--lightweight insulation does not perform this way. The thermal value you get from 18 inches of soil far surpasses the 4.5 R-value (0.25 per inch). The use of earth as a large capacity heat storage makes it possible not only to reduce such buildings’ demand for heating and cooling energy, but also helps to preserve the local microclimate.
